NSW ambos urge caution amid soaring temps

NSW paramedics are urging people to stay cool and hydrated to avoid heat exhaustion as temperatures soar.

Since Friday, the Ambulance Service of NSW has responded to at least 31 people suffering from heat exhaustion and stress.

Cases so far include a 14-year-old boy who was treated for heat stroke after spending all day at the beach on Friday.

Other call-outs have been for nausea, dizziness and fainting, which are all symptoms of heat stress.

NSW Ambulance warns that when heat is combined with a pre-existing condition, it can cause serious illness and even death.

It's encouraging people to check on elderly family and friends.

Heat exhaustion and stress symptoms include nausea, vomiting, fainting, dizziness, loss of appetite, weakness and a headache. Sufferers should lie down with cool wet towels around their neck and under their arms, and should drink cool fluids.
